"I called Carroll Mechanical for an estimate on a new high efficiency heat pump system. I met with a member of their team that clearly explained everything and helped to design a solution that worked for my family at a fair price. The install team arrived on time, they were very polished, and did a technically excellent job. The system is working really well and the whole family is comfortable! Couldn’t have asked for more - I’ll be using Carroll Mechanical as my go to HVAC contractor from here on out."

"I had an amazing experience with JDL.. They were really quick to respond to my request. Charges very reasonably for coming out to troubleshoot my heat pump. Tech (Isak) was punctual, professional, and patient. They originally quoted me for the service and later on they found my system is still under warranty.. Which saved me a bunch of money. I have nothing but good things to say about the whole experience. I recommend them wholeheartedly and will definitely use them again."

"Knowledge on the unit was extensive. They provided important information or recalled parts and reliability of the unit."

"At least 5 other companies said that they could not handle the job because our air handler was in the attic and the opening for our stairs was too small to take out the old handler and put in the new one. Air Master Heating's expert, Ken, laughed out loud about that. He said that it would be no problem. He did calculations and we solved the problem with a high efficiency unit. Ken was the estimator and led the installation team. Everyone on the team was hardworking and respectful. They installed the system, cleaned up well and were a pleasure to have in our home. The system is working great and has been very energy efficient. I would recommend this company without hesitation!"
